-19- for full identification. However, it appears there are (or were) two forms on these islands that Forster could discriminate as different from his P. gavia, although one of them may be equivalent to the subspecies of P. pacificus mentioned above. HYDROBATIDAE. Fregetta melanogaster (Gould). Tahiti: Forster. Under the name of Procellaria fregata Linn., Forster records it "ad littora insulae Otahaitee"; he was here Aug. 16 to Sept. 1, 1773, and from April 22 to May 14, 1774. Oceanodroma fuliginosa (Gmelin). (Type locality: Tahiti.) Tahiti: Latham. ? Taha: Bennett. Wiglesworth (1891) says it is a "species not yet identified by any modern writer." He queried it as possibly the same as Bulweria magillivrayi, but Stejneger (Proc. Nat. Mus., xvi, 1893, 620) determined it as a species of Oceanodroma, on the basis of a specimen obtained from Torishima, Japan, and Salvin (Cat. Birds Brit. Mus., xxv, 1896, 353) thought he was correct in this identi- fication. The species is colored like O. homochroa, but is much larger. Bennett refers to a "Procellaria fuliginosa" or "sooty petrel" he found at the island of Tahaa. Oceanodroma? species. Tahiti: Peale.
